原始语种摘要: Abstract(#br)The ridge push force and the total lithospheric strength of the Nazca plate are compared along an East-West transect from the East Pacific Rise to the Peru–Chile trench at latitude 12°S. The thermal structure of the plate is estimated from the plate cooling model and constrained by heat flow, bathymetry, and geoid height data. The best fitting thermal model has a basal temperature of ∼1600K and an asymptotic plate thickness (not reached because of the relatively young age of the plate at the trench) of ∼101km. The ridge push force, also determined from the plate cooling model, is of the order of 1.5TNm −1 at the trench. The total lithospheric strength as a function of age is estimated for a possible...
